The push button switch connects to the reset line such that the IC is only active when the button is pressed. Requires x3 AA batteries and depending upon desired use a speaker, both available separately.

Description Price Square wave generator kit £3.35 Square wave generator kit with speaker £4.00

	Timer project kit The timer project uses a dual 555 timer, which once started by pressing the button illuminates an LED until the desired time out period has elapsed when a buzzer is sounded. The duration of both the delay and buzzer sound period can be by PCB mounted potentiometers. (Max time period 200 seconds, max buzzer period 10 seconds) Requires x4 AA batteries, available separately.
	Description Price Timer project kit £4.50

	Quiz buzzer project kit Two people (or two teams) can used the quiz buzzer to show who pressed their button first. When the button is pressed the buzzer sounds and either the red or green light is illuminated to show who was fastest. Requires x3 AA batteries, available separately.
	Description Price Quiz buzzer project kit £4.95

7 segment LED display kit This kit uses a binary up down counter IC and a binary to 7 segment display driver IC to operate the 7 segment LED display. Connections to the board allow up or down counting to take place and pre-set value to be loaded. The kit makes a nice table football score board as supplied or an electronic dice if used in conjunction with the square wave generator (Application note available). Requires x3 AA batteries, available separately.

Description Price 7 segment LED display kit £5.10
